- MEANS FOR SE-Al lNG BOTTLES.

SPECIFICATION formingpart of Letters Patent No. 743,636, dated November10, 1903, Application filed December S, 1902. erial No. 138,669. (liemodel.)

To all whom it may concern:

Be it known that I, EWALD GOLTSTEIN, of the city of Cologne, in theGerman Empire,

have invented certain new and useful Improvements in Means for SealingBottles, of which the following is a specification.

To this end I provide means for applying a hollow cap externally uponthe bottle-neck, the said cap being pressed against the outside of thebottle-neck, which is provided with natural or artificialirregularities, by means of the pressure of a medium, such asindia-rubber, which is capable of assuming any shape.

To enable the invention to be fully understood, I will describe it byreference to the accompanying drawings, in which-- Figure 1 illustratesin a sectional view a suitable form of apparatus for carrying out theinvention and a suitable bottle-neck, the section being taken on line -11 of Fig. 2. Fig. 2 is a sectional plan on line 2 2 of Fig. 1; and Fig.3 is a view similar to Fig. 1, but showing the parts in a differentposition with the cap applied to the bottle.

In the particular arrangement shown the india-rnbber has the shape of aring d, held upon the flange c of the cylinder or ring 6'. An internalcylinder e rests with its lower end upon the upper part of the said ringcl. fis a block, the lower surface of which is provided with a concaverecess to receive the hollow cap 0 and is situated within the ring (1under the upper part of this ring. As clearly shown, the said block f isprovided with lateral lugs g g, which pass through slots h 71, formed inthe inner cylinder 6 and rest within recesses or a channel 21, providedin the upper part of the cylinder or ring c. A ring or connectionj isscrewed upon the outside of the upper end of the said ring or cyl inderc, this connection serving to rigidly hold the blockf in the ring c.

The'device operates as follows: The hollow cap or capsule 0 being placedin position within the rubber ring d or on the top of the bottle-neckwith a suitable Washer c for providing ahermetic joint when the cap ispressed down, the bottle-neck is passed into the cap,

and pressure isthen applied to the inner movable cylinder e This firstpresses the indie-rubber ring d downward, and as the ring 6' is rigidlyconnected with the block f by means of the connectionj the pressure uponthe'india-rubber ring is communicated to the top of the cap 0 throughthe said block until the packing ring or disk 0' has been fullycompressed and can yield no further. The ring or cylinder 6 can thenmore no farther downward and further pressure upon the cylinder 6 willcause a relative movement between the said cylinder c and the. ring cl,whereby the india-rubber ring at is caused to bulge inward, so as totightly apply the cap 0 against the sides of the neck of the bottle a,causing it to enter all the inequalities or irregularities therein.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An apparatus for sealing bottles and the like,comprising a casing, an expansible ring therein, a block rigidlyconnected with the casing and extending partly within said ring andpartly projecting therefrom, and an annular compressor arranged to movebetween the said projecting portion of the block and the casing and toengage the end surface of said ring.

2. An apparatus for sealing bottles and the like, comprising a casing,an expansible ring therein,'a block rigidly connected with the casing,and an annular compressor surrounding said block and arranged to exertpressure on said expansible ring.

An apparatus for sealing bottles and the like, comprising a casing, anexpansilole ring carried thereby, a block rigidly connected with thecasing, and a cylinder for exerting pressure on said expansible ring,said cylinder being movable relatively to the block.

4:. An apparatus forsealing bottles and the like, comprising a casing,an expansible ring carried thereby, a block projecting into saidexpansible ring and provided with means connecting it with the casing,and an annular compressor surrounding the block and'provided withlongitudinal slots for the passage of the means which connect the blockwith carried thereby, a block arranged to enter said expansible ring,and provided with outwardly-extending arms, arranged to engage the spacebetween said block and casing, and the casing, a screwoap for lockingsaid arms an expansible ring arranged to be expanded to the casing and acompressor surrounding by said compressor.
